chore(ci): Remove ci-sweep tasks (vectordotdev#17415)

Noticed this still being used in a couple of places that it didn't need to be (it was only useful
for Github hosted runners with tight disk contraints). Once I removed them I found it wasn't being
used anywhere so removed the `make` task.

Saves roughly 3 minutes per test.
